: I recently purchased six Colorado Blue Spruces 5'-6' tall. A neighbor told me his were infected with some type or airborne disease. What can I do to prevent my trees from getting infected?
I wish I knew. My trees are 30 ft high and losing their needles. I think I have the same problem. I have sprayed them with diazinion and several other chemical to no avail.
